Banded Agate Mimics Banded Jasper

Until magnification, each of these banded agates appear to be comprised of the red and yellow jaspers which are so common on The Carver agate field. Magnification (see third photo), however, reveals that these bands are micro crystalline (too small to be seen by the eye alone), e.g., like agate banding. Unlike most of The Carver agates, these agates were not formed in a nodule or geode. My best guess is that they were formed as a vein agate in a crack in lava.
